There's no denying that the desert boot is a timeless menswear classic, but light-colored suede isn't exactly a winter-friendly material. But footwear-master Ronnie Fieg's latest collaboration is a tougher take on the iconic shoe, ideal for winter weather. "The main goal was to stay within the company's range of product and heritage," says Fieg. "It still amazes me how relevant this boot remains over its 60 years of existence." The collaboration comes in three colors—grey, navy and olive—all cut from saddle leather. The very definition of rugged and refined, you can feel the texture in these premium leathers, which apparently ages beautifully. "I've been wearing all three styles for months," says Fieg. "And they all look better now than when I took them out of the boxes."
